Class 12 Evaluation: CBSE Issues Strict OSM Portal Login Orders for Teachers

CBSE OSM Portal 2026: Mandatory Practice Run for Teachers

From February 18, 2026, it is mandatory for all Class XI and XII teachers in CBSE-affiliated schools to complete the On-Screen Marking (OSM) practice run before the actual board evaluation begins. The Central Board of Secondary Education has issued strict monitoring directives to all school Principals to ensure absolute compliance across the country. As of Thursday, February 19, 2026, the board is actively tracking the completion status of every assigned evaluator.

How are OSM portal credentials distributed?

The URL for the CBSE OSM portal, along with individual Log-in IDs and passwords, has been dispatched directly to the evaluators. These credentials have been emailed to the specific email IDs of the evaluators as updated by their respective schools on the official OASIS portal.

What if the practice answer book is of a different subject?

The Board has clarified a common confusion regarding the mock run. Evaluators must complete the mock evaluation simply to acquaint themselves with the digital interface. They must evaluate the assigned copy irrespective of the subject of the answer book, the medium of the language, or any other related issue.

Evaluation Duty and Teacher Salary Projections

Teachers assigned to board evaluation duties receive per-copy remuneration, but their primary financial update comes from their regular salary structure. With the Dearness Allowance (DA) expected to hit 55 percent in January 2026, PGTs and TGTs participating in this evaluation will see a substantial jump in their standard monthly pay.

How much will PGT salaries increase with the new DA?

A Post Graduate Teacher (PGT) generally falls under Level 8 of the 7th CPC Pay Matrix, while a Trained Graduate Teacher (TGT) sits at Level 7. Applying the expected 55 percent DA formula yields the following calculation.

For a Level 8 evaluator, the new DA rate provides an annual gain of Rs 28,560, functioning completely independently of the honorarium received for checking Class XII answer books through the OSM system. Teachers can verify these projections using the 8th pay commission arrears calculator.

Strict Compliance and Exclusions Under the Circular

The Controller of Examinations has explicitly instructed all Regional Directors and Regional Officers to circulate this reminder to all affiliated schools. The board is not treating this mock run as optional.

Which classes are mandated for this practice run?

The directive is strictly aimed at teachers currently teaching classes XI and XII. Principals are held directly responsible for ensuring these specific educators log in and complete the digital evaluation practice.

Are Class X teachers excluded from this portal?

Yes, this specific circular excludes primary, middle, and secondary school teachers who are not assigned to Class XII duties. Teachers exclusively handling Class X evaluations will receive separate directives for their respective checking centers or digital portals.

What happens if a school fails to comply?

CBSE HQ is actively monitoring backend data regarding the completion of the assigned tasks by individual evaluators. In practice, schools that fail to ensure 100 percent OSM onboarding by the deadline often face show-cause notices from their Regional Office, which can severely delay the school’s own result processing later.
